PROBLEM TO BE SOLVED: To provide a compound-type elastic pavement material structure that remains stable over a long period, without a pavement material in a lower layer undergoing physical deterioration even when a top-coat layer has been damaged, at the same time offering sufficient elasticity and changing properties only a little over time.SOLUTION: A compound-type elastic pavement material has a laminated structure comprising integrated lower and upper layers, the lower layer being an elastic layer of a three-dimensional network structure of random loops formed by curving and twisting a continuous linear body made of a thermoplastic elastic resin, the loops being in contact with each other in a molten state, and the upper layer being an elastic layer.SELECTED DRAWING: Figure 1 |
